BRESSER plan achromatic objective lens 100x (Refurbished)

Enter the world of astrophotography now. With the new BRESSER HD moon and planet camera with ST4 autoguider function. This camera is very good for astrophotography with short exposure times, i.e. for celestial objects like the moon, planets or star clusters. For astrophotography with long exposure times for low light deep sky objects, like galaxies and gas nebulae, we recommend the BRESSER Full HD Deep-Sky Camera (Art. No. 4959050) instead, with it's even higher resolution and sensor sensitivity. Equipped with the new high-sensitivity SONY IMX225 CMOS colour sensor, the BRESSER HD moon and planet camera delivers amazing image results with very short exposure times, even with simple telescope equipment. In addition, this ultra-modern camera can also be used as an autoguider, e.g. to actively track the main imaging device with SLR or CCD astro camera. A universal CMOS colour camera that delivers super-sharp lunar and planetary images in particular. The particularly low noise level of this new chip generation from SONY, ensures an exceptionally high brilliance and no cooling is required. Due to the high native pixel resolution of 1280x980, together with suitable telescopes, very beautiful images of the moon, but also detailed planetary images are possible. The ToupSky pro software included in the scope of delivery not only offers the necessary basic functions for image and video recording, but also many helpful special functions for image post-processing and for setting up the Guider. Functions such as live image display, exposure settings, white balance, dark image capture, stacking, timelapse recordings and much more can be individually configured. Especially the very sophisticated software makes it really easy for you to get started in astrophotography. With the automatic settings, you can produce absolutely presentable results without much prior knowledge. If you wish, simply switch off the automatic settings and gradually venture into the individual professional settings. Connect the camera directly to the ST4 connector of your telescope mount and you have fully automatic tracking control. This makes long exposures of several minutes possible without the stars producing unwanted line marks due to the ever-present synchronisation fluctuations of a telescope mount. A corresponding ST-4 connection cable is even included with the camera. Due to the high light sensitivity of the camera, you will always find a suitable guide star even with very short exposure times. For connection to guide tubes or off-axis guiders, the camera has a 1.25" plug-in sleeve, 1.25" filter thread (M28.5x0.6) and C-mount thread (1 "x1/32"). IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10 / 11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

The NEXCOPE NE910 microscope offers excellent optical performance and ease of use, and is ideal for scientific tasks. It is the perfect laboratory microscope for life sciences, histology, microbiology etc., and comes with an attractive price tag. LENSES The planachromatic infinity lenses ensure a flat field of view. Together with the swing top condensor (NA 0.9/0.25), the lenses deliver a high contrast and high resolution over the entire visible spectrum. The nosepiece has six positions and is equipped with four lenses as standard (4x, 10x, 20x, 40x, 100x oil). These feature an M25 thread and a parfocal length of 60 mm. The 40x lens has a spring-loaded protection mechanism. EYEPIECES The eyepieces’ large 25 mm field of view allows you to view a very wide area. The high eyepiece head is ideal for spectacle wearers. A rubber edge provides protection upon eye contact. A dioptre compensation of -5 to +5 can be set individually for each eyepiece. The interpupillary distance can be adjusted between 47 mm and 78 mm. ILLUMINATION The powerful 3 W LED has an adjustable brightness and provides optimal illumination with excellent colour reproduction. The colour temperature stays constant when the light is dimmed. The light is equipped with an Eco sensor that switches the light off when it is not in use. The condensor with an iris diaphragm and swing top is adjustable and provides Köhler illumination together with the light source, which is also equipped with an iris diaphragm. Markings on the knurled ring allow you to adjust the aperture to the chosen lens at any time. The auxiliary lens can be pulled out to quickly switch the aperture from 0.9 to 0.25, e.g. to examine the specimen. This enables efficient and reproducible results. Frosted and neutral density filters can be moved into the beam path with a button press and provide optimal illumination/brightness adjustment without operating the dimmer. MECHANICS The XY stage is moved via a combination of a toothed rack drive and a wire rope hoist. This enables exact positioning for high magnifications. The height of the coaxial control knobs can be adjusted to ensure an ergonomic setup. In addition to the coarse focus, the fine focus helps to render a very sharp image of the object. A full turn of the fine focus moves the table up/down by 0.2 mm. The fine focus can be adjusted with one finger on the right-hand side. The XY stage and focus can be operated simultaneously with one hand. The table height limit helps to protect the specimens and optimize workflows. The large (152x190mm) specimen stage with an impact-resistant Gorilla Glass™ inlay is suitable for all laboratory tasks. It is also resistant to liquids and easy to clean. The friction of the coarse focus can be adjusted to the user. The fine focus knobs are held in place magnetically and can be installed on the left or right side as desired. CAMERA CONNECTION The NEXCOPE NE910 is specially designed for use with c-mount cameras. You can choose from two different adapters, depending on the sensor size: 0.5x c-mount adapter for sensor sizes up to 2/3” 1x c-mount adapter for sensor sizes of 1” As the adapter can be adjusted, the camera image can be matched parfocally to the eyepieces. The beam splitter features three different modes: Eyepieces 100% / Camera tube 0% Eyepieces 50% / Camera tube 50% Eyepieces 0% / Camera tube 100% ACCESSORIES (optional) Lenses: 2x, 60x,Dark field condenser, dry or oil Phase contrast set Differential interference contrast (DIC) Reflected light unit Epi-fluorescence unit Polarisation set FEATURES Professional upright research microscope 6x nosepiece, tilted backwards Lens type: Planachromatic, infinity (60 mm parfocal length, M25) Precise and ergonomic mechanics Outstanding expandability for all common contrasting techniques, as well as fluorescence Bright LED illumination Eco mode Köhler illumination (full Köhler) Integrated matte filter WHAT'S INCLUDED Microscope stand with 6x nosepiece, equipped with four planachromatic lenses (4x, 10x, 20x, 40x, 100x oil) One pair of 10x eyepieces (field of view: 25 mm, Plug-in diameter: 30 mm) Dust protection cover Mains cable
